본 논문에서 사용자를 대신하는 3차원 아바타를 통해서 가상현실 기반 메타버스 콘텐츠를 체험하기 위한 아웃사이드-인 HMD 추적기와 RGB-D 카메라를 이용하는 새로운 전신 모션추적 시스템을 제안한다. 제안된 시스템은 VR 사용자의 머리 및 손 모션을 추적할 수 있는 아웃사이드-인 HMD 추적기와 VR 사용자의 상체 및 하체 모션을 추적할 수 있는 RGB-D 카메라로 구성된다. 제안된 시스템은 별도의 보정 도구를 사용하는 대신 2단계 자동 알고리즘을 통해 아웃사이드-인 HMD 추적기와 RGB-D 카메라를 보정하여 사용자의 머리, 손, 상체 및 하체 모션을 정밀하게 추적할 수 있다. 제안된 시스템의 성능은 실제 실험을 통해 증명하였다.
